Teaching Address Overflow Flags
A Teaching Address Overflow Flag will turn ON if the teaching address is not
within the range of position data addresses allocated to the task after execut-
ing a Teaching Command (17E2 to 17E5 hex) for the Command Area using
the IOWR instruction in the ladder diagram or after turning ON the Teaching
Bit (one for each task: n+3, 09, n+7, 09, n+9, 09).
The above error can occur at the following times.
• The teaching address set for IOWR is not within the range of position data
addresses.
• The following condition was not met when turning on the Teaching Bit.
(Current teaching a Number of axes in task) must be within the
position data range for the task. (The current teaching address is set in
the Command Area, the number of axes in the task is set in the unit
parameters, and the task position data range is set in the memory man-
agement parameters.)
Note The Teaching Address Overflow Flag will not be refreshed immediately after
the IOWR instruction is executed. Check the flag status in the next cycle.
